What Maintenance Do Solar Panels Need?

Solar panels are an increasingly popular choice for businesses and commercial properties, especially in Arizona, due to year-round sunny weather. Like any investment, solar systems require proper care to ensure they perform at their best. Maintenance is essential to maximize efficiency, extend the lifespan of the equipment, and avoid costly repairs down the road.

What maintenance does my solar system need after it is installed? Let's explore the key maintenance requirements for different types of solar panel installations.

Why Regular Maintenance Matters

Commercial solar panels operate under various environmental conditions and are exposed to dirt, debris, weather, and mechanical wear. Without regular maintenance, these factors can reduce their efficiency and lead to potential malfunctions. For example, a thick layer of dust or bird droppings may block sunlight, reducing energy output. Small issues, if left unnoticed, can escalate into major problems that compromise the system's functionality.

Regular maintenance not only ensures optimal performance and energy output but also prolongs the lifespan of your solar system, contributing to higher returns on your investment. By addressing problems early, you can save on significant costs associated with repairs or equipment replacement. Now, let's discuss the specific maintenance tasks depending on the type of solar installation.

Maintenance for Rooftop Solar Panels

Rooftop solar panels are common in commercial properties but are also susceptible to certain challenges, given their elevation and placement.

Cleaning the Panels

Rooftop solar panels often accumulate dust, leaves, bird droppings, and other debris that reduce efficiency. Regular cleaning, at least twice a year, is recommended to maintain optimal energy production. Cleaning frequency may be higher in areas with frequent dust storms, bird activity, or pollution.  Cleaning frequency may be reduced with the occurrence of rain.

Inspecting for Roof Leaks and Structural Integrity

When panels are installed on the roof, it's essential to check for potential damage to the roof's structure. Maintenance should include looking for leaks, loose mounts, or other issues that could affect both the panels and the roof.

Checking Electrical Components

Connections, inverters, and wiring can degrade over time. Periodic inspection ensures that all electrical components are operating safely and efficiently.

Maintenance for Ground-Mounted Systems

Ground-mounted systems are often used for large-scale commercial, industrial or utility scale solar projects. While easier to access than rooftop systems, they have their own unique maintenance needs.

Weed and Vegetation Management

Overgrown grass, weeds, or other vegetation can block sunlight and interfere with panel operation. Regular trimming around the installation is crucial to ensure optimal energy output. Some companies opt for fencing around the system to not only prevent trespassing but also help keep animals and other pests out of the area around the system.

Cleaning the Panels

Similar to rooftop panels, ground mount systems are exposed to dirt, mud, and other debris. These systems typically require more frequent cleaning given their proximity to the ground and dusty conditions.

Examining Supports and Foundations

The mounting structure must be periodically inspected for corrosion, shifting, or instability, especially after extreme weather conditions like heavy rains or high winds.  These systems can be susceptible damage from erosion. 

Maintenance for Solar Carports

Solar carports, which double as shaded parking areas and energy generators, have distinct maintenance requirements due to their unique design.

Panel Inspection and Cleaning

Panels on solar carports gather dust and debris just like rooftop or ground-mounted systems. Routine cleaning is necessary to keep them operating at peak efficiency.

Structural Inspection

Since carports provide shade and provide parking shelter, regular checks of their structural integrity are critical. Look for loose bolts, rust, or damage to support beams that could compromise safety.  These systems can be susceptible to damage from vehicles.

Common Maintenance Tasks Across All Installations

• Visual Inspections: Regularly look for cracks, discoloration, or damage to solar panels. This helps identify issues before they affect performance.
• Monitoring Energy Output: Use monitoring systems to track energy production. A sudden drop in output may indicate dirt buildup from a storm, electrical issues, or malfunctioning components.
• Checking Inverters and Batteries: Inspect inverters for error messages and ensure that batteries (if present) are holding charge efficiently.
